The 300 level was inspected to <br />assure that all significant introduced contaminant sources had been removed from the <br />underground mine. <br />There ie a 14 inch borehole that connects the Storks level to the 600 level; moat of the <br />ground water inflows to the Storks Level pass through this borehole to the 600 level. The <br />borehole is located approximately 200 yards inby of the Storke ad it portal. Any water that <br />might discharge from the Storks adit would flow into a man-way lateral to 5 shaft. <br />The following is a list of 300 level locations that were inspected, along with comments on <br />any pertinent observations that were made (drifts on the 300 level are numbered, with the <br />first number being 3): <br />1. 321 mechanic's shop: mercury vapor lamps, possible PCB containing <br />capacitors, lubricants and fuel, had been removed. <br />2. 319 repair and pipe shops: mercury vapor lamps and possible PCB containing <br />capacitors had been removed. <br />3. Electrical and Engineering Shops: ballasts in fluorescent light fixtures <br />were checked and found to be marked "NO PCB" on the factory labels. <br />4. 311 substation: PCB transformer had been removed, documentation of proper <br />disposal of these transformers has been previously submitted to the <br />Division, oil breakers were drained and the oil tested for PCB with <br />negative results; documentation of the analytical results will be provided <br />to the Division. <br />5. Mobile mechanic's shop. <br />6. 4-shaft fire station: several jugs of "MSA foam concentrate" need to be <br />removed. <br />7. 4-shaft hoist room: several possible mercury vapor lamps need to be <br />removed. <br />8. 319 substation: documentation that oil breakers do not contain PCB needs <br />to be provided. <br />With the few exceptions noted above, the 300 level was found to be free of man-made or <br />introduced contamination sources. Once the few remaining items are removed, and the <br />requested PC8 analytical data provided, the Division would have no problem with closing the <br />300 level. <br />Inspection of the Storks Waste Water Pump Station <br />On 5/16/96, Climax notified the Division of an incident involving enowmelt runoff at the <br />Storks Waste Water Pump Station. This location was inspected; observations and a description <br />of the incident are provided here. A concrete flume located north of the Storke Waste Water <br />Pump Station routes collected runoff and seepage from the Storks Yard into the pump station <br />ponds. There is a trash rack in the flume located just above the pump station. The trash <br />rack had become plugged, primarily with straw mulch from the 1995 seeding effort, causing the <br />flume to overtop and flow into the Arkansas River. As soon as the trash rack was cleaned- <br />out, the situation was corrected. Rapid snowmelt related to unusually high temperatures for <br />the month of May caused high flows to the Storks Waste Water Pump Station. The operator <br />cleaned out ditches and culverts on the hillside north of the pump station and above the <br />
